Earlier in this thread, I asked the question about how long after the second shot a person will be considered fully vaccinated for entry purposes. I realize that most of you don't read Swedish, but there was a recent study,
which was reported by the government SVT channel, of 2,000 young and healthy health-care employees which showed that after three months, 50% of the antibodies produced by Pfizer's vaccine are gone, while 80% of the antibodies from Astra-Zeneca's vaccine have vanished. After seven months, there's an 85% reduction in Pfizer's antibodies. This corroborates the Israeli data. So, if the White House is really going to "follow the science," they need to set a time limit of a few months after the second shot.
